"The Radial J series DI's are easily the most reliable & consistent DI products available to the touring artist. Not only do they deliver a clean signal, they also seem to provide a unique warmth which is essential to The National's sound." - Dessner about Radial JDI.

"The first time a venue provided me with a Radial JDI I noticed an immediate difference, in clarity, presence and fullness. I went and bought my own the next day. I often get comments about how good my acoustic guitar sounds live and I know the JDI is a huge part of that. I can't imagine playing without it." - Osenga about Radial JDI.

At 10:40 of this video clip provided by Gear Gods and from their "RIGGED" series, Chris O'Toole, 2016 bassist of Unearth shows off his rig and points out his Radial JDI.
"From there, we go into a Shure Wireless GLX unit and that goes into this wireless receiver which is also a tuner, so it saves space on your pedal-board. Radial JDI for pure clean signal to the sound guy. He usually just uses this for sort of, bass. Then I've little pick holders here. ...and then that goes into a Darkglass Microtubes B7K Analog Preamp. This thing is essentially the new Sans Amp but it sounds nicer to me. It's a more modern distortion channel, and that is powered by a COIKS Adam Power Supply. That's basically just the smallest, lightest power supply. The cool thing about that one is there is a voltage selector and you can select between 115 and 230 volts for Europe and Australia which is real handy.
Then, we go down to the Amp rig. That goes straight into Mesa M6 Carbine which I use each night. I just got this as well, this Mesa Subway D-800 which is essentially a backup but I've been using it more and more each time and it's a bit more user friendly than this one because this one is just too damn powerful.
That's powered by a little Furman Power Conditioner. That works kind of nice with the lights in back, for dark venues. I use Mesa Road Ready cabs wherever I can. These things are totally over engineered but they're super well made and super reliable. I also put super heavy duty rubber casters on it because it's 210 lbs. as it is"
